Tgall whom it may concern:

Be it known that I, PERCY H. THOMAS, a citizen of the United States, and resident State of New Jersey, have invented certain new and useful Improvements in Operation of Vapor- Converters, of which the following is a specification.

:In certain applications for Letters Patent of the United States, namely application Serial Number 140,353, filed January 24, 1903, and application Serial Number filed. May 6, 1903, I have shown and described a system of supplying constant current to direct current translating devices from an alternating current source through the medium of one or more vapor converters. I have still another application Serial Number 276,672, filed September 1st, 1905, of which this application is a division in which are shown modified arrangements of circuits serving this same purpose.

The object of the present invention is to provide certain improvements in the system described in said applications, such improvements relating to features which will be described hereinafter and more particularly pointed out in the claims attached hereto.

My invention is illustrated in the accompanying drawing which is a diagram of one embodiment of the present invention.

The regulator used for controlling the current strength in cases of constant current operation is often connected in the circuit of the transformer primary, and it is readily seen that the changes of load in the consumption circuit automatically effeet the regulator which in turn acts in a manner to compensate for such changes. It may be desirable under such conditions to place a regulator of this sort in the secondary circuit of the transformer, in which case I may make the circuit leading from each secondary terminal to a positive electrode of the vapor converter contain one element of the compensating device in the form of a coil, both coils acting upon a common core or being otherwise magnetically connected. Such an organization is illustrated in the drawing wherein a transformer primary is shown at 59, and the secondary therefor is shown at 60. A11 intermediate point on the secondary is connected as shown through a The positive electrodes, 65 and 66, of the converter 62 and joined to the terminals of the secondary 60, through coils, 67 and 68, respectively, and the said coils are in operatlve relation to a magnetic core, 69, and are capable of adjustment up and down on the vertical portions of the said core, in response to changes of load in the consumption circuit, the principle being that of the well known Baker regulator. The coils, 67 and 68 are wound directly upon and supported by a yoke, 70, and the magnetic pull as between the said coils and the core, 69, is counter-balanced by a weight, 71, on a lever, 72, pivoted at 73. The Baker regulator here referred to is well known in the art and involves among various principles the use of an adjustable inductance and means for mechanically balancing the magnetic pull of the adjustable inductance in any position so long as the current in the coil remains at a definite value. The adjustable impedance usually involves a core movable relatively to a coil and mechanical means for neutralizing the pull on said core or said coils at a predetermined current. Reference may be had to certain patents to Malcolm H. Baker as follows, 748,144 to 748,149 inclusive, December 29th, 1903, and 762,114 June 7th, 1904.

I claim as my invention i 1. The combination with an alternating current supply, a vacuum rectifier, a choke -coil and work circuit receiving direct current from said rectifier, of connections from the terminals of the source to the rectifier and from an intermediate point of the source to the rectifier through said coil and work circuit, together with impedance coils with movable cores in the first named leads and mechanical means for balancing the pull on said cores at a predetermined current.

2. In a system of electrical distribution, the combination with an alternating current source, a vacuum converter comprising an hermetically sealed and completely exhausted container, a vaporizablereconstructing cathode and a plurality of anodes therein and connections from the anodes to the terminals of the source and from the cathode to an intermediate point of the source, said connection including a sustaining device, of symmetrical coils in the first named connections, together with movable cores for said coils attached together and having the sum of the individual forces produced thereon by a predetermined current balanced for all positions by a mechanical force.

3. In a system of electrical distribution, the combination with an alternating current source, a vacuum rectifier, comprising an hermetically sealed and completely exhausted container, a vaporizable reconstructing cathode and a plurality of anodes therein, and an impedance 0011 having a movable core'in each lead, its magnetic pull for a definite current being balanced against an equal mechanical force, of a work circuit and suitable connections from the anodes to the terminals of the source and from the cathode ,to an intermediate point of the source, together with suitable sustaining means.

4. In a system of electrical distribution wherein constant current translating devices are supplied from an alternating current source through a transformer and through one or more vapor converters, means for .regulating the supply to the translating devices on the secondary side of the transformer, such means consisting of separate coils interposed between each terminal of the secondary and a vapor converter and a regulating device operated by the said coils for securing constant current in the consumption circuit. a

In a system of electrical distribution, the combination with a source of alternatelectrodes,

ing electric power, a vapor rectifier comprising an exhausted container, a plurality of anodes and a vaporizable cathode vtherefor, and connections from said source to said of impedances adjustable through the mechanical movement of parts thereof in the leads of the several anodes and-means for mechanically inter-linking such movements in the several impedances, together with a work circuit in the connection from the cathode to the source.

6. In a system of electrical distribution, the combination with a source of alternating electric power, a vapor rectifier comprising an exhausted container, a plurality of main anodes and a vaporizable cathode therefor, and connections from said source to said electrodes, of impedances adjustable through the mechanical movement of parts thereof in the leads of said anodes and means for mechanically inter-linking such movements in the several impedances, together with a work circuit in the connection from the cathode to the source.

7. In a system of electrical distribution, the combination with a source of alternating electric power, a' vapor-rectifier comprising an exhausted container, a plurality of main anodes and a vaporiza'ble cathode therefor, and connectionsfrom said source to said electrodes, of impedances in the leads of said anodes, means for varying said impedances individually, and means for inter-linking said varying means.
